FRANK J. VAN COTT, OF UNADILLA, NEW YORK.

SILO-BEENFORCING STRUCTURE.

Application filed March 5, 1921. Serial No. 449,908.

T all whom it may concern Be it known that I, FRANK J. VAN Corr a citizen. of the United States, and a resident of Unadilla, in the county of Otsego andState of New York, have invented a certain new and useful Silo-Reenforcing Structure, of which the following is a specification.

j The object of my inventionis to provide a reenforcing structure for silos, which is of simple, durable and inexpensive construction, and can readily and easily be installed on any silo. 1

More particularly my invention relates to a reenforcing structure for circular buildings, which when installed may be adjusted. or moved to position where the wall of the circular building will retain a true circle- ;in form, the parts being so arranged that the upper end of the silo or circular building will be rigidly braced against move ment in any direction whatsoever.

Another object is to provide inclined rafters which are fixed to the upper end of the circular wall, the upper ends of the rafters being held together, and members placed between the lower ends of the rafters, for holding them at proper spaced intervals.

The lower ends of the rafters are connected together by an adjustable tension device. The tension device and upper ends of the rafters being connected together so that an inward "exertion may be applied to the wall at the lower ends of the rafters.

Still another object is to provide spacing members which are fixed to the upper end of a silo wall and adapted to have their ends abut against each other, and means for exerting an inward pull on the silo wall, the

40 spacing members preventing movement of the' silo wall at the points where they engage the silowall, thusfixing several points of the silo wall in a true circle.

Still another object is to providespacing members which are fixed to the upper end of a silo wall and adaptedto have their ends abut against each other, and means for exerting an inward pull on the silo wall, the spacing members preventing movement points of the silo wall in a true circle, and filler blocks curved from end to end fixed to the spacing members for preventing an of the. silo wall at the points where they, engage thesilo wall, thus fixing several inward movement of the silo wallbetween the ends of the spacing members.

Still another object is to provide holder devices adapted to support the ends of the spacing members and to receive the lower ends of the inclined rafters, thus fixing the rafters and spacing members against movement relative to each other, and a centeringdevice spaced equidistant from the ends ofthe rafters and connected to the holder devices by rods, the rods being provided with screw threaded portions whereby adjustment'may be had for pulling the holder devices towards the center.

Still another object is to provide on the outer side of the holder devices hook ortions adapted to receive the upper end 0 the anchoring cable.

Still another object is to provide inclined rafters held together at their upper ends by a member having a peripheral flange under which is extended the roof boards, spacing members arranged to rest between the ends of the rafters and filler blocks, fixed to the spacing members and adapted to have one edge rest against the inner surface of the silo wall for preventing the inward movement of the silo wall and help it retain its circular form, and a hoop extended around the outside of the silo wall for preventing expansion or outward movement of the silo wall.

With these and other objects in view, my

. invention consists in the construction arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 is a central, vertical, sectional view taken through my improved roof structure. v

Figure 8 is a top or plan view of a modified form of my reenforcing device.

Figure 9 is a perspective view of the holder used in connection with the form of my device shown in Figure 8.

Figure 10 is another form of my reenforcing device; and

Figure 11 is a central, sectional view, taken on line 1111 of Figure 10.

In the accompanying drawings I have used the reference numeral 11) to indicate generally a circular wall which may be of wooden staves or any other suitable material. 1n the drawings 1 have shown the circular walls as made up of wooden staves.

The upper end of the wall 10 is bevelled as at 11. Inclined rafters 12 are provided which have their lower ends abutting against the wall 10.

In order to hold the rafters together at their upper ends I have provided a member 13 which is provided with a series of sockets 14 in which are received the ends of the rafters 12. The sockets 14 hold the upper ends of the rafters in proper spaced relationship to each other.

A peripheral flange 15 is provided on the member 13. Roof boards 16 have their upper ends placed below the flange 15, and have their upper ends abutting against the member 13.

The lower ends of the roof boards 16 are fixed to the beveled surface 11 of the wall 10, and have their lower ends projected out beyond the sides of the wall 10.

The member 13 is provided with a central opening 17 through which is extended a rod 18 having the screw threaded ends 19. Nuts 20 are provided on the screw threaded ends 19. The purposes of the rod 18 will be hereafter more fully set forth.

Hoops 21 are placed around the outside of the wall 10 for preventing expansion thereof.

Holder devices A are placed over the upper edge of the wall 10. The upper end of the wall 10. at the place where the holder de v ce A is placed thereover, is provided with a horizontal upper edge instead of the bevelled edge as illustrated in Figure 1 of the drawings.

Each of the holder devices A is provided with an outer side member 22 and an inner side member 23. The silo wall 10 is received between the inner and outer side members 23 and 22.

The upper ends of the side members 22 and 23 are connected together by a plate 24.

It will be seen that a substantially yoke shaped portion is formed by the sides 22, 23-

and the plate 24. The plate 241 is provided with an opening 25, as illustrated in Figure 6 of the drawings, the purpose of which will be hereafterfully set forth.

Extending inwardly from the side 23 are the socket members 26 which are spaced rela tive to each other. I

'lhesidesof the socket member 26 are provided with registering openings 27.

The sides 22 and 23 are also provided with registering openings 28.

The holder devices A are placed over the upper end of the silo wall. 10 and the inclined rafters 12 have a portion of their lower end received in the opening 25 and the balance of their lower ends abutted or rested aga nst the inner side of the silo wall and in between the spaced sockets 26.

It will be seen that the adjacent edges of plate 24 will prevent sideward movement of the lower end of the rafter 12. The lower end of the rafter 12 may be bolted or nailed to the upper edge of the wall 10.

In order to properly space the lower end of the rafters and prevent any movement of the rafters or holder device A, I have provided spacing members 29 which have their ends received in and supported by the socket members 26.

The ends of the spacing members 29 abut against the rafters 12, as illustrated in Figures 1 and 2' of the drawings.

A bolt 30 may be extended through the openings 27 in the sockets 26 and through the spacing member 29 for holding the ends of the spacing members in positon and against any possible movement.

From the construction just described it will be seen that I have provided rafters which are fixed to the silo wall and have their lower ends properly spaced apart and held in that position against any possible movement.

The spacing members 29 form chords relative to the circle of the silo wall. The upper edge of the members 29 are curved from end to end as at 31, as illustrated in Figure 1 of the drawings.

The curving of the upper edge of the members 29 makes it possible to have the edge 31 rest against the roof boards 16 at all points. The roof boards 16 may be also nailed to the spacing members 29.

The outer side 22 of the holder device A is provided with a hook portion 32 which receives the upper end of the anchoring cable 33. A. clamp 34 on the cable 33 locks the cable to the hook 32.

By anchoring the upper end of the cable '33 to the holder device A it will be seen that 1 have provided a place to anchor the upper end of the cable which willbe rigid and very effective.

A centering member B spaced equidistant from the ends of the rafters is provided tending flange/36.

The flange 36 is provided with which has a bottom 35 and an upwardly em a plurality of openings through which are extended the inner ends of the rods 37 which extend ra- V108 B. V

The inner ends of the rods 37 are-screw threaded as at 38 for receiving nuts 39. The nuts 39 are received on the end of the rod 37 which is within the centering device B.

The outer ends of the rods 37 extend through the registering openings 28 in the side 22 and 23 of the holder device A, and

through a' corresponding opening 40 inthe silo wall 1O. i i

The outer. end of the rods 37' are also screw threaded. as at 41. and receive the nuts 42.

It will be seen that by tightening the nuts 42 or 39 on the rods 37 that the silo wall may be pulled. inwardly or towards the centering device B.

An opening .43 in the bottom 35 of the centering device B permits the lower endv of the rod 18 to extend therethrough. "When the rods 37 have been tightened then the screwing of the nuts 20'on the rod 18 will cause the centering device and the mem-- ber13 to be drawn towards eachother and held in their drawn position.

the centering device B and the rods 37 tend to pull the silo wall inwardly, thus forming a ;very rigid construction and insuring the silo wall-at the points where the rafters engagethe wall against any movement-what soever. i

In order to prevent. any inward move ment'of the wall 10 between the end of the rafters I have provided filler blocks 44 which arev curved from end to end on their. outer edge so as to conform to the inner surface of the circular wall '10.

; The tiller blocks 44 are fixed to the-lower edge of the spacing members29 by anytsuitable means.

The silo wall 1O may be nailed to the filler blocks 44. i y

:By the use of the filler blocks 44 I am positively assured of no inward movement of the wall '10 between the lower ends ofthe rafters 12, thus giving me a means of reinforcing the inner'surface of the silo/wall against any undesired. inward movement retain its true form.. 1 i

It will be understood that inmany cases when silos are blown down it is due tothe and alsomaking it possible -to rhave the silo shaped causes a portionof the stavesto leave their position in the circle, thus making git.

meet is an advantage because when pressureis applied toone side of the silo it is equally distributed by means of my roof structure, so that to a reat extent pressure at one point on the wa l issubstantially eliminated.

In Figures 8 and 9 I have shown a slightly modified formof device in which I use a holder device C which comprises socket portions 45-and the yoke portion 46. The yoke portion 46 is designed to extend over the upper edge of the circular wall 10.'

Spacing members 47 are provided which are similar to the spacing members: 29 and have their ends received in the sockets 45. The ends of the spacing members 47 abut against each other.

registering openings 48, and through the openings formed in the wall 1, and the ends of the spacing members 47. i

Filler blocks 44 are fixed to the spacing members 47 and hold the wall 10 against inward movement between the holder devices C.

In this form of device it will be seen that when the centering device B is-tightened that .it will cause the ends of the spacing members 47m abut against each other and form a brace against any'inward undesired movement. i r v In FigureslO and 11 I have shown the filler blocks 44 serving as the spacing mem bers for holdingthevwall:rigid and against' movement. The filler blocks .44 have their ends 50 abutting against each other so as to 7 form a wedge against inward movement of the .wall whlch rests against their outer curved edge. 1

'In order to prevent outward movement of the parts I- have provided a member 51 similar-in construction tothe filler blocks'44.

The members 51are placed against the un-.

derside of the filler blocks. The members 51 are staggered relative to the filler blocks so that the abutting ends of the filler blocks come at the point where the strength of the,

In'order to further brace the filler blocks.

and members 51 I employ a saddle device53 which is S-shaped in cross section.

The saddledevicehas one of its ends lap ping over the abutting ends of the filler blooksa'ndthence under them and "over the center of the members 51 and terminates on the underside of the member 51.

A bolt 54: connects the ends of the saddle device 53 so as to prevent movement thereof relative to the filler blocks or members 51,.

The advantages of my device are that 1 am able to completely reinforce the silo wall against inward undesired movement and to provide such a roof structure that will act as a reenforcingmeans for preventing the inward movement of the wall.

My device is simple and can readily and easily be installed and the holder device forms a means for holding the parts together and in proper position relative to each other, while the rafters and spacing members are being installed and permanently locked.

My device can at any time be adjusted for tightening the various parts and for always holding the wall 10 in its true form, that is, circle.

It will be understood that the silo wall expands and contracts, due to the swelling and shrinking of the staves. lVith my device it will not in any way seriously interfere with the wall 10 and cause it to become loosened from its form, because. 1 am able to tighten the outside hoop and then adjust my improved device which will lock and hold the silo in its true form. r I

It will be understood that where Ih'a've used the term silo wall, that I do not intend to be limited to silo walls or silos, as my improved structure may be used for any circular wall building.

Some changes may be made in the con struction andarrangement of the details of my device without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure. or use of mechanical equivalents, which may be reasonably included within their scope.
